What has the GOP become, part 2?

If the Republican Party were a normal party, it would take advantage of this amazing moment. It is being offered the deal of the century: trillions of dollars in spending cuts in exchange for a few hundred million dollars of revenue increases.

A normal Republican Party would seize the opportunity to put a long-term limit on the growth of government. It would seize the opportunity to put the country on a sound fiscal footing. It would seize the opportunity to do these things without putting any real crimp in economic growth.

The party is not being asked to raise marginal tax rates in a way that might pervert incentives. On the contrary, Republicans are merely being asked to close loopholes and eliminate tax expenditures that are themselves distortionary.

This, as I say, is the mother of all no-brainers.

But we can have no confidence that the Republicans will seize this opportunity. Thats because the Republican Party may no longer be a normal party. Over the past few years, it has been infected by a faction that is more of a psychological protest than a practical, governing alternative.
